A telescope system (10) has an intelligent motor controller (50) for accurately controlling telescope position to facilitate location of celestial objects and to precisely control the speed at which the telescope moves to facilitate tracking of celestial objects. An optical encoder (62) utilizes two photodetectors to provides enhanced servo control of the telescope positioning motors (52), a calibration circuit eliminates a need to test LED's during assembly of the optical encoder (62) and a brushless mount provides electrical communication to an altitude drive motor (85) located in a fork (19) thereof in a manner which mitigates problems due to undesirable wrapping of an electrical cable around the mount as the mount rotates in azimuth.

La présente invention concerne un système de télescope (10) doté d'une commande de moteur intelligente (50) destinée à positionner avec exactitude un télescope afin de faciliter la détection d'objets célestes et de commander avec précision la vitesse à laquelle le télescope se déplace de manière à faciliter le suivi d'objets célestes. Un codeur optique (62) utilise deux photodétecteurs dans le but d'obtenir une servocommande améliorée des moteurs de positionnement (52) du télescope, un circuit d'étalonnage élimine le besoin de tester les diodes électroluminescentes durant l'assemblage du codeur optique (62) et un montage sans balais fournit de l'électricité à un moteur de commande d'altitude (85) placé dans une fourche (19) du montage d'une façon qui élimine les inconvénients dus à enroulement gênant d'un câble électrique autour du montage lorsque le montage tourne en azimut.
